YE LI E&M CO.LTD Product Lines We Repair
Our engineers are trained on the full YE LI E&M CO.LTD product range. Below are the major product families we service.
YE LI Standard AC Motors
Three-phase and single-phase AC induction motors in IE2 and IE3 efficiency classes. Common repair issues include bearing wear, winding insulation degradation, shaft misalignment, and overheating due to inadequate cooling in dusty Indian manufacturing environments.
YE LI Soft Starters and Motor Controllers
Electronic motor starting devices and variable frequency drives for precise speed control and power factor optimization. Repair focus includes thyristor failure, gate drive circuit faults, cooling fan malfunction, and firmware calibration issues common in harsh industrial settings.
YE LI DC Motors and Servo Systems
Brushed and brushless DC motors with integrated control electronics for positioning and precision motion applications. Typical failures involve commutator wear, brush spring degradation, encoder malfunction, and control board solder joint cracks from vibration.
YE LI Brake Motors and Geared Systems
Motors with integrated electromagnetic brakes and gearbox assemblies for hoists, cranes, and conveyors. Repair challenges include brake coil burnout, gearbox bearing seizure, brake pad wear, and shaft seal leakage in high-temperature environments.
YE LI Motor Protection and Thermal Relays
Overload relays, thermal protectors, and motor circuit breakers for equipment safety. Common faults include contact oxidation, bimetallic strip calibration drift, spring fatigue, and false trip activation in fluctuating supply conditions typical of Indian power grids.
YE LI Frequency Inverters and Drives
Variable frequency drives ranging from 0.75 kW to 75 kW for fan, pump, and compressor energy optimization. Repair issues include IGBT module failure, capacitor degradation from heat, display panel malfunction, and parameter reset required after power surges.

Common YE LI E&M CO.LTD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in YE LI E&M CO.LTD equipment arriving at our workshop.
- ✓Stator winding insulation breakdown in YE LI motors — Moisture ingress, thermal cycling, and inadequate ventilation in Indian coastal and humid manufacturing zones cause breakdown of the polyamide insulation system. Phase-to-phase or phase-to-ground faults develop over 12-24 months of continuous operation.
- ✓Soft starter thyristor gating failure and no motor start — YE LI soft starters rely on gate drive optocouplers that degrade under thermal stress (45-50°C ambient heat common in enclosed Indian panel cabinets). Loss of gate signal prevents thyristor firing and motor engagement.
- ✓Frequency inverter DC bus capacitor short and no display — Electrolytic capacitors in YE LI drive front-end rectifier stages suffer accelerated aging from ripple current stress and Indian ambient temperatures exceeding 40°C. Capacitor ESR increases and internal shorts trigger protection shutdown.
- ✓DC motor brush and commutator arcing with sparking at brush contact — YE LI brush-type DC motors develop commutator surface pitting and brush wear grooves from prolonged operation under heavy load. Arcing and sparking emerge as brush pressure drops and contact resistance increases non-uniformly.
- ✓Motor thermal overload relay nuisance tripping during normal operation — YE LI thermal relays lose calibration accuracy when bimetallic strip tension weakens or contact surface oxidizes. Drift of 5-10% causes false trip points mismatched to motor thermal time constant, especially in monsoon-affected humid regions.
- ✓Brake motor electromagnetic coil burnout and brake slippage — YE LI brake coils overheat when winding insulation degrades or coil cooling airflow is blocked by dust buildup common in textile mills and cement plants. Coil open-circuit results in total brake loss and hoist load drop risk.

Frequently Asked Questions — YE LI E&M CO.LTD Repairs
Do you repair YE LI E&M CO.LTD equipment anywhere in India?+
Yes. Synchronics repairs the complete YE LI E&M CO.LTD product range including AC motors, DC motors, soft starters, frequency inverters, brake motors, and motor protection relays. We provide PAN India door pickup from Mumbai, Delhi, Pune, Hyderabad, Bangalore, Chennai, Kolkata, Ahmedabad, and all tier-2 and tier-3 cities. All repairs are completed at our ISO-certified facility in Vadodara, Gujarat.
What is the typical repair turnaround time for a YE LI soft starter or frequency inverter?+
YE LI soft starter repairs typically take 4-6 working days for component diagnosis, board-level repair, and function testing. Frequency inverter repairs (IGBT replacement, capacitor bank replacement, firmware reload) take 6-8 working days depending on spares availability. We provide daily progress updates and offer expedited 24-48 hour turnaround for critical production line equipment at a premium.
Can you supply spare parts for YE LI E&M motors and drives?+
Synchronics sources genuine YE LI spare parts directly from Chinese distributors and maintains stock of high-demand items: motor bearings, brushes, commutator segments, thyristor modules, gate drive optocouplers, and electrolytic capacitors. We also stock alternative OEM-equivalent components from Siemens, ABB, and Schneider for warranty-backed replacements where YE LI originals face long lead times or obsolescence.
How does YE LI motor repair differ from Siemens or ABB repair at Synchronics?+
YE LI motors use simplified winding configurations and lower-cost insulation systems compared to premium brands, which means repair strategy emphasizes cost-effective restoration. Our engineers are trained on YE LI-specific failure modes (bimetallic relay drift, capacitor ESR degradation in tropical climate, and soft starter optocoupler aging). We leverage YE LI's standardized motor frame sizes and spare parts compatibility to minimize downtime for Indian textile, cement, and logistics sectors.
Do you repair YE LI equipment under warranty or OEM service agreements?+
Synchronics is an independent repair house and does not hold YE LI authorized service agreements. However, we repair YE LI equipment at significantly lower cost than OEM service centers (30-40% savings) and deliver same technical rigor with 24-month warranty on all parts replaced. For equipment under original manufacturer warranty, we provide post-warranty repairs and upgrades to extend asset life by 5-7 years.
How do I send my YE LI E&M CO.LTD unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a YE LI E&M CO.LTD drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on YE LI E&M CO.LTD repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your YE LI E&M CO.LTD unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
